Abstract
The invention relates to a polyvinylidene fluoride polymer having an ultra-high molecular weight, and unexpected physical properties. The ultra-high molecular weight polymer is clear, has a lower melting point, reduced crystallinity, excellent impact resistance, and a high elongation at the yield point. The ultra-high molecular weight polyvinylidene fluoride can be alone, or blended with other polymers, in final applications and articles.
